Exchange 2003 not sending emails
Yesterday morning our exchange server stoped sending emails, we can recive e-mails and everything else on the network works fine, but it just point blank refuses to send emails, it just ques them.
I did think that it was our DNS at first as i had modified it to allow us to view a few school websites in our area that are not in our external DNS but need access to, though after checking the fault started befor i had even touched the DNS so it cant be that.
I cant see Anything oviouse in the Event Viewer, it happned between 8:46 and 9:14 yesterday as the email i sent at 8:46 went through but the one at 9:14 didn't. didnt do the DNS till after lunch.
just to add, sending e-mails internally works fine, its at the point where the e-mails need to leave the school it just failes.
